Engine oil VALVOLINE or OEM Audi

OEM Audi Engine oil

I run the 5w-40 in my 2004 Audi A8 and both of my power strokes just because it's handy and the diesel grade oil is overall better than the other synthetic I was running in a 0w-40 weight.

Pros: diesel grade oil, better
Vehicle: Audi A8

VALVOLINE Engine oil

I'm using "Valvoline Modern Engine Oil" since they have patents and claim to have some chemistry there to keep the valve stems more carbon-free.

Pros: carbon-free valve stems
